The TWebBrowser component (located on the "Internet" page of the Component Palette) provides access to the Web browser functionality from your Delphi applications. In general, you'll want to enable saving of a web page displayed inside a WebBrowser as a HTML file to a disk.
Saving a web page as a raw HTML
If you only want to save a web page as a raw HTML you would select "Web Page, HTML only (*.htm, *.html)". It will simply save the current page's source HTML to your drive intact. This action will NOT save the graphics from the page or any other files used within the page, which means that if you loaded the file back from the local disk, you would see broken image links.
复制代码
uses ActiveX;

procedure WB_SaveAs_HTML(WB : TWebBrowser; const FileName : string) ;
var
   PersistStream: IPersistStreamInit;
   Stream: IStream;
   FileStream: TFileStream;
begin
   if not Assigned(WB.Document) then
   begin
     ShowMessage('Document not loaded!') ;
     Exit;
   end;

   PersistStream := WB.Document as IPersistStreamInit;
   FileStream := TFileStream.Create(FileName, fmCreate) ;
   try
     Stream := TStreamAdapter.Create(FileStream, soReference) as IStream;
     if Failed(PersistStream.Save(Stream, True)) then ShowMessage('SaveAs HTML fail!') ;
   finally
     FileStream.Free;
   end;
end; (* WB_SaveAs_HTML *)
 
Usage sample:
 
//first navigate
WebBrowser1.Navigate('about:blank') ;

//then save
WB_SaveAs_HTML(WebBrowser1,'c:\WebBrowser1.html') ;
